I have a channel balance with the horizontal markings "27 5" followed by vertical markings "B.S.1.", followed by horizontal markings "O B". I see two different series on your website for 28 inch channel balances and don't know which to order.

Thanks for posting. Sounds like you have a 28" block & tackle balance with a stamp option of 2750. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
